Mission 5 lua script error

[mikeguy]

Heya reflected.  Enjoying the campaign so far!  While attacking the fighters taking off from the aerodrome the game crashed with the following script error.  Some script errors I'm able to press ok and continue.  This one crashed the game.  I'm not sure if that's relevant or not, but thought I'd bring it up in case it helps.  Let me know if I can give any more info.
